[0003] However, the following problems exist:

[0004] 1) The existing self-cleaning filter adopts open form, and the filtering chamber cannot form a closed state, if in rainy state, rainwater will enter the filtering system, causing the filtering element to be damp and the resistance to rise;

[0005] 2) The filtering element of the existing self-cleaning filter has two types: one is cylindrical, which has large structural resistance and general dust removal effect;The other is a combination of cone and cylinder, which is better than the cylindrical shape;

[0006] 3) The existing filtering element has poor applicability, and for high humidity and hydrocarbon-containing working conditions such as heavy fog, the resistance is high, which affects the system. INVENTION CONTENTS

[0036] To better understand the above-mentioned technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Combination Figures 1 to 3 As shown, the present invention provides an energy-saving self-cleaning filter for all-day use, including a housing 100.

[0038] The outer casing 100 has a clean chamber 1 and a filter chamber 2 connected to the clean chamber 1 inside.

[0039] The bottom surface of the filter chamber 2 is provided with a primary filter screen 3 as an air inlet, and the outer side of the filter chamber 2 is provided with an air inlet grille 4, which is configured with an inertial separation structure.

[0040] Multiple filter elements 5 are installed in the filter chamber 2. All filter elements 5 are arranged horizontally, and the air outlets of all filter elements 5 are connected to the clean chamber 1.

[0041] The clean chamber 1 is provided with an air outlet pipe 6 on one side, and a connecting flange is arranged on the port of the air outlet pipe 6, so as to be connected with the equipment to be filtered on site.

[0042] The top of the outer shell 100 is provided with a slope.

[0043] The bottom of the outer shell 100 is further provided with four supporting legs 7.

[0044] The four supporting legs 7 are respectively connected to the four corner positions of the outer shell 100.

[0045] The upper end of the supporting leg 7 is connected to the bottom of the outer shell 100 through a bolt.

[0046] The lower end of the supporting leg 7 is connected to the ground of the installation position through a bolt.

[0047] The four supporting legs 7 are connected and fixed through connecting rods.

[0048] The filter elements 5 are all provided with a double-cone structure and are arranged in an array in the filter chamber 2. The arrangement mode and the number of the filter elements 5 are shown in the following table:

[0049] rows columns number of filter elements 2 2 4 3 2 6 4 2 8 3 3 9 4 3 12 4 4 14 4 5 20 4 6 24 4 7 28 4 8 32 4 9 36

[0050] The number combination of the filter elements 5 is selected according to the requirement of the equipment to be filtered. The air inlet amount can reach 50m 3 / min~2000m 3 / min.

[0051] The filter element 5 adopts a double-cone structure, so that the dust is more easily detached, and the dust cleaning effect is better.

[0052] The filter element 5 is made of synthetic fiber and is implemented by using a special processing technology. The filter element 5 has high filtration grade, small structural resistance, and long service life. The filter element 5 can be applied to all-weather working conditions and is particularly suitable for high-humidity and hydrocarbon-containing working conditions.

[0053] The differential pressure gauge 8 and the electric control box 9 are arranged on one side of the outer shell 100.

[0054] The slope of the top of the outer shell 100 is set to 5~8°, so as to prevent water accumulation on the top.

[0055] The air inlet grille 4 is provided as a whole. The filter elements 5 can be replaced by disassembling the air inlet grille 4, without the need for personnel to drill into the inside of the filter chamber 2 to operate, so that the safety and reliability are high.

[0056] In combination Figure 4 and Figure 5As shown, the inertial separation structure of the air inlet grille 4 comprises an outer frame 401, a plurality of connecting rods 402 horizontally arranged in the outer frame 401, and a plurality of baffles 403 arranged in the outer frame 401 and interposed on the connecting rods 402.

[0057] The transverse cross sections of the baffles 403 are all arranged in a wave shape.

[0058] The adjacent sides between the baffles 403 are all provided with separation grooves 404, the openings of the separation grooves 404 all face the outer side of the filter chamber 2, and the separation grooves 404 on the opposite sides between the baffles 403 are arranged in a staggered manner.

[0059] The inertial separation structure utilizes the change of airflow direction, the water droplets have a larger mass and stronger inertia, and cannot quickly turn with the airflow, so that the water droplets are collected by the separation grooves 404 after entering the inertial separation structure, and are separated from the air due to the inertia (the separated air enters the filter chamber 2 through the gaps between the baffles 403). The water droplets have a larger mass and stronger inertia, and cannot quickly turn with the airflow, so as to impact the surface of the inertial separation groove 404 and be captured.

[0060] When the airflow containing water droplets passes through, the water droplets impact the surface of the separation groove 404 due to inertia, adhere and gather into larger water droplets, and finally flow into the outside of the filter chamber 2 along the separation groove 404 under the action of gravity.

[0061] The inertial separation structure adopts a special aluminum alloy hydrophobic coating to reduce the adhesion and retention of water droplets and promote the rapid diversion of water flow.

[0062] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation on the present application, as long as the changes and variations of the above described embodiments are within the scope of the present application.
